Reasons Why Our Compound Turbos Work So Well

• A lot more cool air enters the cylinders, because the dual staged compressors work together within their most efficient zones. The boost air is typically over 100 cooler per pressure made than from a single turbo.
• The air entering the cylinder is at higher pressure, bringing the boost pressure and exhaust drive pressures near a 1:1 ratio.
• The intake stroke can actually produce power.
• There are additional air molecules in the cylinder which do not get involved in combustion which carry the heat out of the cylinder (similar to how a jet engine is cooler).
• It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.
  Diesel Power Source compound turbo 5.9 cummins turbo kits are all designed on CAD/CAM Software, using CFD (Computational Fluid Dynamics) Testing. Our Cummins compound turbos give a factory-like fit with the highest performance possible. Everything fits like it was built from the factory, and performs so well. You’ll wonder how you ever drove without them.
